To all into m may concern:

Be it known that I, LEWIS KALLING,'Of the iity of Baltimore and State of Maryland, have invented certain Improvements in Sealing--Caps for Bottles, of which the following is a specification. This invention relates to improvements in sealing caps for bottles, of the description in which the cap is secured to the bottle'head by a reduction in its diameter, andwhich contains a compressible joint-forming appliance consistin may be desired. The said invention consists in a peculiar either of a ring or a disk as formation of the sealing cap whereby the oint-forniing eppiiance is held in contact with the crown of the cap, and the vertical weil or flange of the cap given a certain elastici ty which adapts it to fit bottle heads differing in diameter, as will hereinafter fully appear.

- hereof, and in which,-

Figure 5. an enlarged vertical central section of the upper part of a bottle provided with a seaiing; esp constructed in accordance with the present invention, and showing the cap it appears before the scaling operetion. Fig. 2 is aview similar to Fig. 1 except that the cap is shown as it appears subsequent to the sealing, operation. Fig. 3 is a top vie. Y of the blank from which the sealing cap formed. 4 is a top view of the cap es shown in li' ig. 5 is a top view of one form of the chit-forming appliance or gasket. v

Referring now to the drawing, 1 is the ho'tt end having the annular lip or shoulder (4.

The sealing cap comprises the crown b and (1 which. extend. radially from the blank 3 shown in Fig. 3, end-which are ultimately introverted or turned inward so to produce a flGKlblG and compressible inner surface o linin in the flan e a of the on as to I: 1

shown in lliige..l and 2.

forced slightly under the nnnu By reference to Figs. land 2 it will be seen that the j oint forming gasket is a flat device, which in Fig. 1 is shown as held. against the inner surface of the crown by the points of the prongs d.

In the sealing operation which consists in closing the cap over the bottle head, the prongs (1 being independent and yielding (levices, separately adapt themselvesto the contour of the parts of the bottle head with which they are broughtin contact; and the prongs at the curvature f where they are wider and less flexible than at the white, are lar lip or shoulder a and form a system of locks which offer resistance to the removal of the cap.

It is within the scope of the invention to use either an annular or a disk j oint-f'orming gasket; and also to form the prongs d of any desired shape, and length with respect to the depth of the flange, as the invention consists in the formation of the cap with a flange having a double'elastic wall, or a flange havgreater elasticity than the outer wall whereby it is adapted to readily adjust itself to-the shape of the bottle head, and in doing so reduce with the annular lipof the'bottle head, a system of locks.

I claim as my invention 1; In combination with a sealing cap comprising e cro'wn'and a pendent flange adapted, for attachment to a bottle head provided with an annular lip or shoulder, s

jointierming gasket placed within, the cap and in contact wlth t e crown thereof, and a multiplicity of prongs vwhich extend from the edge of the said flange and have their oints in contact with the said gasket whereiiy the same is held in place, substantially as specified:

2. In combination with a bottle having an annular lip 'or shoulder a sealing cap comprising a crown and a pendent flange rovided with enn ltiplicity of prongs w ich are inturncd so as to produce an inner wall or lining for the flange which is expansible and compressible independently of the flange roper, and a joint-forming gasket which is ieli Within the cap by the said prongs,.sub-
